Abstract

In this research, we studied curing and filler systems for preparation of fast cure SMC and low-density SMC, respectivly. Two curing systems were evaluated for fast cure SMC formulation. One is a mixed initiator system and the other is an activator system. For low-density SMC, glass micro-baloon(GMB) was used as a filler. Various SMC formulations were cured in an appropriate way, and their curing behavior and physical/mechanical properties were characterized. Curing rates were increased with increasing quantity of mixed initiator and activator, but mechanical properties were not affected. As the quantities of GMB increased, density and mechanical properties were decreased.

본 논문에서는 속경화 SMC와 저비중 SMC를 제조하기 위한 경화시스템과 배합시스템을 연구하였다. 속경화 SMC를 제조하기 위한 경화시스템으로는 혼합개시제를 사용한 시스템과 촉진제를 사용한 시스템으로 나누어 실험하였고, 저비중용 SMC는 glass micro-baloon(GMB)을 충진제로 사용하여 실험하였다. 본실험에서는 두시스템으로 제조된 시편으로 경화 거동, 기계적 성질, 물리적 성질 등을 측정하였다. 속경화용 SMC 시편의 경우는 혼합개시제의 양 및 촉진제의 양이 증가할수록 경화 속도는 증가하였으나 SMC 성형 시편의 물성은 큰 변화를 보이지 않았다. 저비중용 SMC에서는 GMB의 양이 증가함에 따라 비중이 감소하였으며, 물성치에서도 약간의 감소를 보였다.
